Interview process

HR intro call, then a few technical rounds covering LeetCode-style coding and a deep dive on past projects. The interviewers were knowledgeable and friendly. It felt a bit rushed, with tight timeboxes, little time for questions, and limited feedback between stages.

Software Engineer

Helsing·Sep 2026

“It started with a recruiter call, then a technical screen, a live coding round, a system design round and a final conversation about values and mission. The recruiter explained each stage clearly and replied quickly. The interviewers were sharp and engaged, and it felt like a real discussion. The main downside was the gap between the technical rounds and the final round. It took over a week, with little news in between.”
